[PATCH] staging: r8188eu/core: remove the check for NULL pointer in _rtw_enqueue_cmd()
Remove the check for _rtw_enqueue_cmd(), because
rtw_enqueue_cmd() already has a check of NULL pointer,
so this condition is not possible.

[PATCH v8 3/4] drm/bridge: anx7625: add MIPI DPI input feature
The basic anx7625 driver only support MIPI DSI rx signal input.
This patch add MIPI DPI rx input configuration support, after apply
this patch, the driver can support DSI rx or DPI rx by adding
'bus-type' in DT.
